By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
If you think you can do it, you can.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Only the educated are free.
Be gentle to all and stern with yourself.
Who seeks shall find.
Leap, and the net will appear.
If you've got a talent, protect it.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
